Corrosion, Durability & Chemical Tests

Eyeglasses are usually made of plastic, metal or netural materials. No matter which type of materials are used for making a frame, it shall NOT conatin material that's known to cause irritation, allergy and/or toxic reactions on the skin of USERS in a normal state of health.

In EYEWEAR industry, we do expect to consider the following people as users when handling a eyeglass frame:

End-users wearing the frame

Opticians adjust the fitting of an eyeglass frame for the consumers

Assemblers edge and glaze the lenses onto the eyeglass frame.

In addition, we also highly concerned about the frame's coating and coloring quality which is an important criteria to determine the quality level of an eyeglass frame.

REACH CONCERNS: There is no clear instruction how to test frame of sunglass, spectacles and eye protector to confirm the areas contact with skin are free of RESTRICTED SUBSTANCES. According to our experiences, the following recommendations are made:

Restricted substances on metal parts of a spectacle / sunglass frame (recommendation only, please refer to updated requirements from REACH directive): total lead on paint, total cadmium on paint, nickel release.

Restricted substances on plastic parts of a spectacle / sunglass frame (recommendation only, please refer to updated requirements from REACH directive): total cadmium, PHK and total phthalets in plastic components

Restricted substances on SOFT plastic parts of a spectacle / sunglass frame (recommendation only, please refer to updated requirements from REACH directive): SCCP, Phthalates, PHK, total lead and total Cd.
